Select by Performance – Learn More: Light Reflectance

The " light reflectance " of a surface is its ability to reflect light.

Day light and electrical lighting represent the two primary sources of lighting available in the workplace. The light reflectance
of the ceiling, floor and wall surfaces play the second most important role for overall illumination of the room, thus also
directly affecting working comfort and productivity.

Armstrong offers a wide range of products with high light reflectance (>85%)

The measure of light reflectance is the fraction of the specified incident light which is reflected by the surface. It is
measured as a percentage, with a mirror's value being 100% and zero indicating no reflection at all.

The light reflectance of Armstrong ceilings is measured in accordance with ASTM - E1651-94 entitled Standard Test Method for
Total Luminous Reflectance Factor by Use of 30/t Integrating-Sphere Geometry (Germany DIN 5036).
